5.7‑inch TFT LCD Display Module – 320×240, 24‑bit RGB Interface, 4:3 Aspect Ratio

Product Overview

This 5.7‑inch TFT LCD module delivers bright, vivid full‑colour graphics at a resolution of 320 × RGB × 240 pixels with a classic 4:3 landscape aspect ratio. Driven by the HX8218 + HX8615 dual‑chip controller (or equivalent), it features a 24‑bit RGB parallel interface, enabling high‑speed data transfer for smooth video and graphic updates.

The panel is normally white, transmissive with a 12 o’clock viewing direction and a glare surface, offering excellent brightness and contrast for indoor applications. With a large active area of 115.2 × 86.4 mm and a robust module size of 141.12 × 101.55 × 6.05 mm, this display is ideal for instrumentation, control panels, and embedded systems requiring a mid‑size, high‑visibility screen. Its wide operating temperature range (‑20°C to +70°C) ensures reliable performance in industrial environments.
